Has anyone used Powergloss on a dark color car and went right to FP II ? I recently purchased PG, IP and FP II and I'm still playing around with them. I detailed a dark red pickup the other day and used Powergloss followed by Intensive poilsh and then Final Polish II. The truck came out incredible, but I was wondering of the IP in the middle was really necessary? Could I have gone straight to the FP II with out any swirl marks? Thanks!
